If you ever wondered how come fans are typically not allowed into press conferences to personally address professional athletes and team personnel, let the video clip above serve as Exhibit A.

Credit the Dallas Mavericks for allowing some fan interaction during their presser held last week to introduce all seven of the players the team acquired this summer.
